Abstract
A screw-free drawer structure includes a front board, a rear board, two side boards, and a bottom board. The side boards are foldably connected to opposite sides of the bottom board. An upper end of a junction of each side board and the rear board is detachably connected through an elastic fastener that is in snap-fit with a fastener hole. A junction of each side board and the front board is detachably connected through an elastic expansion member that is elastically expanded to be in snap-fit with an engaging hole. Therefore, the screw-free assembly of the drawer structure is realized, and the assembly of the drawer structure is convenient and easy.
